TAMPON MADE OF NON-WOVEN FABRIC BY SELECTIVE NEEDLE-PUNCHED METHOD Russian patent published in 2014 - IPC D04H1/22 A61F13/15 

FIELD: medicine.

SUBSTANCE: method and device for producing absorbent tampons with a reduced number of loose prominent fibres comprises a new needle-punched assembly. The method involves the stages of producing a continuous length of non-woven fibrous fabric; separating single portions of the non-woven fabric from the continuous non-woven fibrous fabric; forming sharp side edges of the single portions of the non-woven fabric; rolling the portion of the non-woven fabric to form a substantially cylindrical piece part of the tampon to form the absorbent tampon. The sharp side edges of each portion of the non-woven fabric are formed by a needle-punched method applied to long side edges of each single portion of the non-woven fabric directly by rolling both the long side edges inside to form the sharp side edges of the single portion of the non-woven fabric and needle punching of the rolled long side edges to fix the sharp side edges of the single portion of the non-woven fabric. The portion of the non-woven fabric is rolled along an axis of rotation substantially in parallel to the width to form the substantially cylindrical piece part of the tampon having an insert end and a removal end.

EFFECT: producing the absorbent tampons with the reduced number of loose prominent fibres.
